Previewing Fin lets you safely see your setup in real time, so you can ask Fin questions, review its reasoning, and confirm that your configurations work as expected.

Use the Preview panel while training Fin to observe how it applies your content, guidance, attributes, procedures, escalation rules, and deployment settings before going live.

Understanding the preview panel

The Preview panel is your main tool for manual, in-context testing. You’ll find it throughout Fin’s training areas — including Content, Guidance, Attributes, Escalation and Procedures — where you can experiment with updates without impacting customers.

Tip: You can also send Fin images or screenshots through this preview to see how Fin Vision recognizes these and provides support.

Preview as a specific user or audience

At the top of the Preview panel, you’ll see the Testing as dropdown. This lets you choose if Fin should simulate a specific user or audience during your test.

Note: You need "Can access people, companies, and account lists" permission to test the Fin preview as a specific users.

User or lead: Preview as a specific user or lead, with access to all relevant content, guidance, and automations (including tasks, data connectors, and custom answers). If you choose User or lead, you’ll be able to configure additional preview settings:
- Select which user or lead you want to test as.
- Choose to use sample data or access real user data for connected integrations.
- Select a brand to preview content and guidance that are brand-specific.
- Choose a language for testing multilingual experiences.
Audience: Test Fin as audience(s) you've configured for Fin, with audience-specific content, guidance, data, and tasks.
Preview user (default): Preview with all live content, guidance, data, and tasks enabled, without impersonating a specific customer.

Previewing as a specific audience also allows you to safely validate answers for internal testers before making them available to customers:

Go to Fin AI Agent > Fin settings > Audiences.
Click New audience and name it something like Internal testers.
Define your audience rules—for example, Email contains @yourcompany.com—then click Save.
Apply this audience to your content/data/guidance/task Fin audience.
Then go to Fin AI Agent Train > Content, open the Preview panel, and preview as a user who matches your Internal testers audience.
Once you’ve confirmed everything works correctly, update or remove the internal audience to set it live for customers.

Tip: Using an unlisted public article (not in your Help Center) and applying an internal audience is a safe way to validate how Fin interprets new content before making it available to customers.

Choose a preview language

Click the settings icon in the preview to choose one of your supported languages and see how Fin responds in that language. If you select Auto, Fin will automatically detect the language of your question.

Customer view and event logs

The preview panel shows two tabs:

Customer view shows what the customer will see.
Event log shows Fin’s reasoning process, including which content, data, etc. it used to generate its response.

The Customer view shows you how this conversation would appear in the Messenger.	The Event log will show any conversation events that are happening in the background, e.g. any Fin personality, Guidance, Tasks, etc. that Fin has applied to the conversation.

You can also switch between the Chat and Email preview to see how Fin answers over email.

Note: All conversations created in Preview will appear in your inbox. These test conversations are excluded from reporting.

Where to use the preview panel

You’ll find the Preview panel in all of Fin AI Agent’s training settings, where you can view how specific features and configurations will appear to customers.

Preview Fin content

In Fin AI Agent > Train > Content, you can use the Preview panel to ask Fin questions and confirm it’s pulling answers from the right sources. This helps you validate that Fin’s responses match your support content, guidance, and connected data.

Preview Fin Guidance

In Fin AI Agent > Train > Guidance you can create or edit guidance, use the Preview panel to ask Fin questions and check how your updates are applied. When you’re satisfied with the results, click Save and Enable to make your guidance live.

Note: All guidance types—draft, paused, and live—are included in preview testing. You don’t need to save or enable guidance to test it.

Preview Fin Attributes

In Fin AI Agent > Train > Attributes use the Preview panel to:

Test Fin Attribute values against example customer messages.
Check how accurately Fin applies the right value.
Iterate on names and descriptions before enabling.

Preview Escalation Rules and Escalation Guidance

In Fin AI Agent > Train > Escalation you can preview both Fin’s Escalation Rules and Escalation Guidance safely before they affect real customers.

Preview a new Escalation Rule

Navigate to Fin AI Agent > Train > Escalation.
Add a condition to the Escalation Rule that targets your email (e.g., Email contains @yourcompany.com).
Click Save and Enable.
Go to the Preview window on the right and set the Testing as user to an email that matches your condition (e.g., your-email@yourcompany.com).
Type a message that should trigger the rule and check the Event log tab. You'll see a confirmation that your rule was correctly followed.
Once you've confirmed it works, you can remove the email condition to activate the rule for customers.

Preview new Escalation Guidance

Go to Fin AI Agent > Fin settings > Audiences.
Click New audience and name it something like Internal testers.
Define audience rules (for example, Email contains @yourcompany.com), then click Save.
Then go to Fin AI Agent > Train > Escalation and apply this audience to your Escalation Guidance.
In Preview, test as a user who matches that internal audience.
Once you've confirmed it works, you can update the audience condition to activate the escalation guidance for customers.

Preview Fin Procedures

In Fin AI Agent > Train > Procedures you can use the Preview button in the top right to see how the procedure will trigger, review Fin’s process, and view the output your customers will receive.

Tip: Previewing procedures is helpful for manual, end-to-end testing as it creates a preview conversation in the inbox where other follow-up actions or automations will be applied so you can preview the customer and teammate experience. You can use Simulations to test a procedure without creating a conversation.

Preview in Deploy

Even if Fin is not yet deployed, you can preview the customer experience from Fin AI Agent > Deploy > Chat in the Preview section.

Or, to preview Fin over email, go to Fin AI Agent > Deploy > Email, click Copy address and send a test email from your Intercom-associated address. You can also use the Preview user dropdown to test how Fin responds to different customer types.
